Abstract

Abstract:

【Objective】Planting density is an important factor affecting pod quantity and quality in rapeseed. Based on a certain number of rapeseed pod quantity, the quality of rapeseed kernels was improved to further tap the potential of rapeseed production, so as to explore the effect of kernels quality on the formation of rapeseed population yield.【Method】The experiment was conducted to investigate the effects of planting density on rapeseed yield, canopy, and pod characteristics during the 2021 to 2022 and 2022 to 2023 growing seasons in Shiye Experimental site of Yangzhou University in Zhenjiang. Qinyou10 and Ningza1838 were used as the rape test materials. Five planting density levels were set as 2.4×10⁵ plant/hm² (D1), 3.6×10⁵plant/hm² (D2), 4.8×10⁵plant/hm² (D3), 6.0×10⁵plant/hm² (D4), and 7.2×10⁵·plant/hm² (D5). 【Result】As planting density increased from D1 to D5, the number of pods in population and plot seed yield initially increased and decreased thereafter. The number of pods in population in D3 and D4 was higher than that in other densities, and plot seed yield reached the maximum value in D2 and D3. The canopy thickness, ranging from 41.50 cm to 80.98 cm across different treatments, increased with an increase in planting density from D2 to D5. The pod density, ranging from 0.98×10⁴ to 2.16×10⁴ per cubic meter, significantly increased as planting density increased. According to the number of seeds per pod across different treatments, the pods were categorized into low efficient pod (≤14), middle efficient pod (15 to 17), and high efficient pod (≥18), respectively. The average yield per pod of low, middle, and high efficient pod was 19.40×10^-3, 53.41×10^-3 and 80.62×10^-3 g, respectively. The allocation ratio of pod number ranged from 27.60% to 40.96% for low efficient pod, 8.39% to19.73% for middle efficient pod and 39.31% to 63.28% for highly efficient pod, respectively. Among the three types of pods, the ratio of yield for highly efficient pod was the highest and the range of variation for low, middle and high efficient type was from 8.41% to 15.62%, 7.24% to 22.01% and 62.60% to 83.92%, respectively. As planting density increased from D3 to D5, the quantity and allocation ratio of highly efficient pod significantly decreased, resulting in decreasing seed yield. 【Conclusion】When the target seed yield was 4 500 kg·hm^-2, the appropriate planting density and population quality indicators with suitable sowing date were as follows: planting density ranged from 3.6 to 4.8×10⁵plant·hm^-2, the number of pods in population ranged from 83.0 to 94.0×10⁶·hm^-2, and the allocation ratio of high efficient pod (≥18 seeds per pod) is more than 50%. Increasing the number of seeds per pod to improve the quantity and allocation ratio of highly efficient pod was an effective way to further enhance the seed yield in rapeseed.
